citizen oi the United? States, residing at lrigngston, Vin the county of Luzerne, State of Pennsylvania, have invented certain new and useful lmprovements 1n Line Chalkers;

f and l do 'hereby declare the following: to he Vtaken in connection wit a' full. clear, and exact description of the invention. such as will enable others skilled in the art to which. it appertainsto make and use the same.

VYY'1"his invention relates to new and useful improvementsidmarlring devices` and particularly to Vchalk lines.

fTheprineipal object of the invention is to provide a device for applying chalk to the Yplenishin'gzgV the chalk.

r'hrrfurther object is to provide a device. of this character which is so formed that. when netinuse, theiline can be wound thereon. the device earring as a spool. i

In the drawing:

Figure 1 is an elevation'of a line chalker made in accordance with the present invention.

Figure 2 is a vertical longitudinal central sectional view through the device the compressing ball being in elevation.

Figure 3 is an enlarged sectional view through the compressing ball, showing the recesses in the op esite sides ofthe ball."

The portion of the outer end wall of each cap ll and l2 which surrounds the ejfelet is depressed inwardly toward the casing'. as shown at 24. Secured to the outer Face of the said end wall of each cap is a disk 25, haw'ingxf` a recess 26 iu llie fare which lies against the cap wall, and in the enter or" thc` dish is a small line receiving' owning il?. surrounded hy a recess 2P?. llisiiosed within each recess 2S is a rubber dish 29 having a central minute opening 29. through which the line is disY posed. the portion el said rubber disk. opposite the recesses being arranged to he flexed hack and forth from one recess to ehe other. as the line is drawn through the casing and dish. Vfrom either direction. These ruhhor disks serve to prevent escape of the powdered chalk from the casing. because of the faut that the openings therein are slightly smaller than the diameter of the chalk line. and therebyY fit snugly.

It will he seen that when the line is secured to a roof, or other place to be marked with a chalk line the operator grasps the casing and moves the same toward the other end of the line. with the result that as the line runs through the casing;r the same Will draw some o the powdered chalk into one of the recesses ot the lead sphere, compres sing the Chalk into the line, any excess o chalk on the line being wiped therefrom by the walls of the small opening of the rubber disk 29. As the chalk is used, the spring 1 tua- 23 forees thejelisk 2O he chalk, thereby maintaim g-teghn, slightly eomp'essed or compactY e and preventing anyY n Y Y I to sift through the openings in the ruhber disks these latter being the only mealsfo' if egress from the casing'. It will also be noted that the casing may he drwnfoward either end of the line, with equally effective chalking of the line.

The casing l0, in combination with Vthe end caps li and l2. forms a spoolV (into weich the line may he Wound, when the dei'ice is to he placed in the pocket of the .orkman o1' in the toolbox.
